Answer:
Jaw saw an average of 6 birds each day
Step-by-step explanation:
Given: One day, Jean saw 7 birds. The next day, she saw 11 birds. The next day, she saw no birds.
To find: average number of birds Jean saw each day
Solution:
Average is a central value of a set of terms.
Average of terms is given by
Number of birds, Jean saw on day one = 7
Number of birds, Jean saw on the second one = 7
Number of birds, Jean saw on the third one = 7
So,
average number of birds Jean saw each day =
Therefore,
Jaw saw an average of 6 birds each day
Divide by 2 to get
5^x = 7
Now take the logarithm.
x·log(5) = log(7)
x = log(7)/log(5) ≈ 1.209062
Answer:
A. (3.14)( 3) - (3.14)
Step-by-step explanation:
volume of the cone that can be filled with flavored ice = volume of cone - volume of the bubble gum
volume of cone = h
where r is the radius of the cone and h is its height.
volume of cone = x 3.14 x x 3
= 12.56 cube inches
volume of a sphere =
where r is the radius of the sphere.
radius =
=
radius = 0.25 inches
So that;
volume of the bubble gum = x 3.14 x
= 0.06542 cube inches
Thus,
volume of the cone that can be filled with flavored ice = 12.56 - 0.06542
= 12.49458
The volume of the cone that can be filled with flavored ice is 12.5 cube inches.

Answer:
B) (x,y) -> (-x,y)
Step-by-step explanation:
By reflecting across the y axis, all y values stay the same, therefore no matter what happens to the x, the second half will be y -> y
Because of the reflection across the y axis, you are simply taking all x values and multiplying by -1 to get x -> -x.
Thus, (x,y) -> (-x,y)
